Of the 9,540,437 shares of common stock of Telos Corporation covered by this Amendment No. 1 to Schedule 13G, 9,264,804 are held directly by The JRP Settlement and 275,633 are held directly by the estate of John Porter.

Clover Management Limited, Ariane Slinger, and Odilo Javier Otero are the directors of Toxford Corporation, and any two together could exercise voting and investment power over the common stock of Telos Corporation previously held by Toxford Corporation, and therefore they had shared voting and investment power over the common stock of Telos Corporation previously held by Toxford Corporation; Ariane Slinger and Odilo Javier Otero together, or either of them with another named signatory of S.O. Clover Management Limited, can act on behalf of S.O. Clover Management Limited, the entity director of Toxford Corporation. Shirley Porter, as the sole Protector of The JRP Settlement, can replace the Trustee and therefore has sole voting and investment power over the common stock of Telos Corporation held by The JRP Settlement. Brian Padgett, Oliver Hemmer, and Ronan Kuczaj are the individuals who can make decisions on behalf of the Trustee and each can act alone in doing so, and therefore they have shared voting and investment power over the common stock of Telos Corporation held by The JRP Settlement.
